To all whom 'it may concern.' V

Be it vknown that I, Avoarii KA-pr- MAN, a citizen of the United States, residing at New York, in the county and State of.

New York, have invented a new and useul (i)il-Lainp, of which the following isa speck fication.

This invention relates to lamps, and es pecall to that class adapted to burn a min eral oi as kerosene, preferably with im incandescent mantle; and the objects of my invention are: first, to provide' a retort, or vaporizernrwith a specially-constructedy gas outlet whereby from the vaporiaer to the air mixing chainher and burner Ywith a minimum danger of clogging; second, to provide means to hold the cleaning needle and valve stem, in certain alinement with, the outlet at all times,"especially when assembling and'even under-intense heat; and, third, to provide a lain .of the character described which will` mi cap to' manufacture, and eicient in use. The invention is illustrated in the accompartying drawing, in which- Figure 1, is a central, vertical section of a lamp constructed according to my invention, with theI mantle omitted, and other parts broken away in part,` the v iew being taken on the line 1-1 of Fig. 2; Fig. 2, is a transverse section onthe line 22 of Fig. 1; and, Fig.-3,`is a view on an enlarged scale of `the gas outlet from.the\`,-vaporizer, and of the valve seat, stein, and, cleaning needle, the parts being in vertical section except the valve stem and needle.

to hold the same in positipn,

warming the entering air, and .protecting the vaporizer, with the following parts of4 In carrying out' the invention I provide anoil lamp, which may have aibrackenas 4,

i special construction: The retoit,` or vapor- I; 1. Uvaporizer,

izer 6, is provided with the `chamber- 7 into ,which oil may flow through the pipe 8, and

assageway 9. In this chamber the o il i cated in any desired manner until thesam' commences to vaporize when the gas gener-A lated will pass out at the top of the retort, or

into the .air mixing tube 10, having the air inlet ports 11, where the gaswill he mixed with air in theproportion desired,

i and the greater part of this mixed gas and air will passlthrough the chamber 12, and screens 13, to be consumed Within an incandesc nt mantle (not shown) as will be readily understood.` \A part vof the gas and air the gas will `be delivered a gallery 5, for' entering the chamberl 12, will flow downwardy through the ports 14., and will becon sumed within the chamber 15, around the retort, thereby keeping the retort heated siiiiciently to continue the gasification of the pilas ,long as desired.

' A@ Irefined mineral `oi1 .of the heavier grades, such as kerosene,have considerable substance .which will but partially vaporize, and will' clog the valve, or port, as usually mtructed, for the discharge of gas from the vaporizer, I have` designed a port and valve of special construction. As shown, the retort 6,'is provided with a closed end, or head 16, of considerable thickness, from which rises the externally screw-threaded collet 17, on which may be screwed a nut- 18, havingfaport opening 19; and the collar 17,

is pwmd'ed with a seat 20, as may be clearly ingy a centrally bowed art 22, e under side cit-'which forms a va ve seat for the valve stem 23which may be raised vertically without turning b the apparatus 24, as shown ,in Fig to t e osition indicated in dotted lines in Iiig. he valve stein 23, carriesa needle 25, adapted to pass through the port 426, iii the plate 21, notfor closing purposes, but for cleaning, as 't e needle is slightly smaller in diameter an the ort. This port is closed by the seating o stem 23 in 2te valve seat Aormed bythe bowed part of the plate 21.

W'ithin the collar 17, a chamber 27,.is formed; and I provide a plurality of inclined passageways 28, through the head 16, which lead from the retort chamber 7, to the chamber 27; and these passageways are inclined at such an angle as to direct the 'gas ent-erin the chamber 27, frointhe retort, against thcside's ofthe part 22, forming the 'valve seat whereby the valve seat is `kept clean from sediment. Y

By making the dischargedport a plate, it isaii easy matter to provi e a'. 'new ort at any time, and "it is easy also erin a proper seat for' the valvestem; andv'byproin alinement with the sides of they valve seat, and the chamber 27, the valve is easily kept clean. These features are very important in a lamp of this kind.

The next important feature is to provide means to hold the valve stem and needle carrier in a vertical plane with the valve seat and port, as the heat applied to the amiamo@moyennant Patentednug.` 29, 1911. d animan mer my 12, isn. amara. mais. l n

e geen inFig. 3in which rests a late 21, hav-` the valve A iooI viding the inclined passageways in the head l retort will readily dis-tort a valve stem.

Then, too, as the needle in practical use is a 'very delicate part and easily broken, byproviding meanslto absolutely `center the same at all "tirnes,a'nd especially when as-v seinblingthe parts, this lgeakage will be ,avoided which now occursVr then the needle is slightly out of perfect alinel'nent. lVith the above in vie\v,-I provide a double means toA insure the holding of the valve stem in proper position.:l First, l-piovidef a tube 29, extending from a plugv `30, closing the bot,- toln'of the retort, to a socket 3l, in the head 16, ivithin` which tube the valve stem.V closely so that it can not warp. Then, too, 1s the yvalve stemt passes through the head 1G, it is lnade to fit' 'snugly within the pas*- sageivay 32, so that even if the tube 29, did not extend into the head 16, the ,upper part of the valve sten'1'\vouldy be heldiin vertical alinenient. l

Another vahiablo lftaiture is 'thev 'Collar 33, on the retortf6.l 'll'iis-collar viiia'de of a diameter-to tithloselyvith'i'nthe,tube forming ,the 1el'iainber '12, lit being `what lnioivnhs ,theiliurner tube, and tlie'eollar is eutavvayon the 'sides ytoA form three ports as clearlv shown inf Fig'. 2', 'so Ithat airl may 'enter 'tliei 'ehanibei' 15, to support 'they combustion y'o'.l" tlie .gaaf around the retort thus provided toL holdthel burner tube 34,
